There are only a handful of viable VM technologies they could possibly use. You've got ESX, Hyper-V, and Xen, that's about it. The type of attack you'd use against each would be different, but you could try all three - though realistically it probably isn't hard to figure out what technology a particular cloud provider uses. Just check their job listings and see what skills they are looking for.
